Specification of Letters Patent. Patented J une 21, 1910,

Application filed July 6, 1909. I Serial No. 506,091.

' To'all whom "it may concern:

- the United States, residing the county of Cookand btate of Illinois,

Be it known that we, WILLIAM Franc J 01in LUTZ and HARRY D. BARTLETT,cltizens of at Chicago, in

have invented new and useful Improveor'drain-pipe connected with thelower-ex-- ments in Packing, of which the" following is a full, clear,and exact description.

This invention. relates to means for tightly calking theconnectionbetween closets, drains, .and the like and the waste-pipe orsewerage-pipe adapted to be secured thereto. Its object is to provide asuitable packing forthis purpose that will be absolutely airtight andwater-tight when in its completed position, and which will fit the partsin such manner that they are not liable to become accidentally separatedor dislodged owing to any warping or stretching of the pipes or thesettling of the building in which the work is placed. This isaccomplished by the means and in the manner. hereinafter fully describedand as more particularly pointed out in the claims.

In the drawings :Figure 1 is a central vertical section of the upperendof a waste tended nose of a closet-bowl, and showing the improvedpacking in position therein.

Fig. 2 is a plan view of said packling removed from the connection anddrawn to about the same scale. Figs-3 and 4 are .transverse verticalsection showing diagrammatically the parts of the packing in scale, inorder to betterillustrate the normal assembled form and drawn to anenlarged position of the packing andfthe shape it usually assumes whenunder compression inthe connection. i v

Referring to. the drawings, it will be noted that A represents the endortion of the usual sewerage drain pipe t at terminates at about thelevel of the floor and has its end edge a preferably flanged outwardly,substantially as shown,- to form a slight shoulder or flare to the---end of said p1 e.

' This shoulder is adapted toform a stop or a suitable annular washer Bthat preferably rests .on the floor and supports the end of saiddrain-pipe, and limits inner circums ferential edge I) deflected or.flanged at an obtuse an' le to the lane of said washer so that it W1llfit snug y against the shoulder or flare a of the pipe abovementioued.The nose 0 of the bowl is preferably slightly and make a tight fit.

-which surrounds said rin per end of the pipe and between the same andthe flange of the bowl, a suitable packing ring D .is placed upon theupper end edge of the pipe where it ma be partially seated in the recessor seat ormed by the flanged edge a of. said pipe. Thus, when the bowlis inserted into place and is forced down so tightly into the pipe, thepacking ring D will spread inthe manner hereinafter pointed out and sealthe connection against the escape or passage of air or water in eitherdirection. The washer B has its periphery provided with severalholes orrecesses 1n alinement witlisimilar openings in the lateral basal flangeof the bowl and in order to tighten the. latter in position,

suitable headed bolts 1) are passed through said openings and the partsdrawn-tightly together by suitable nuts on the upper ends of said bolts.t r

The packing above referred to consists,

vljsreferably, of aflat annular metallic-rin of substantially the sainediameter as Sai drain-pipe and may be made ofzinc, copper, or the like,or, if desired, it may be of some suitable. cast metal. This ring isadapted to hold in shape and be partially surrounded by suitable packingmaterial the outer covering of which is a tubular woven fabricapproximately U-shaped in cross-section made full in the portions e, e,thereof, that are disposedon its upper and lower surfaces and on itstop, bot;- tom, and inner edge. T ese' -por-. tions 5 form suitableannular-receptacles or I spaces wherein is adapted to be inserted and.acked a quantit of asbestos, ground cork, Y air, or any we l-knowncalking material, having the portion that passes around the inner edgeof the ring free from material excepting the woven fabric. This providesa. soft addin in the space between the crotch ormed tween thefloor-flange and nose of. the bowl and the upper flared end ofthedrain-pipe both. above and below the ring D and maybe oiledand sprinkledor coated with. graphite or ,plumbago to preserve the same.

It will be noted,by particular reference to Fig. 4:, that when thepacking is compressed the filling material both above and below the ringwill be displaced and forced into the empty space in the tubular fabricbetween the inner edge ring and the outer sur face ofsthe nose of thebowl. This is caused by the outward movement of thefilling being limitedand restricted by the non-expansion of the outer portion of the fabric,and the compression on the packing, being exerted on both sides of' thering simultaneously, any lateral movement or expansion :of the packingmaterial must take place be tween the nose or the bowl and the innercircumferential ed e of the ring in the man tubular woven abricsubstantially 'U-shapedin cross section having the ends of its separated portions enlarged and a fillerof suit-- able material insertedtherein.

a 4. A packing comprising a metallic ring and a covering surrounding thesame on its upper and lower sides and its inner circumferential edge,and having the portion thereof above and below the ring enlarged ascompared to the portion surrounding the edge of said ring.

5. A packing comprising a metallic ring and a covering surrounding thesame on its upper and lower sides and its inner circumferential edge andhaving the portion thereof on the edge of said ring reduced in thick- 7,ness, and having the portions thereof on the upper and lower sides ofsaid ring provided with suitable packing materia L 6. A packingcomprising a metallic ring and a tubular woven fabric coveringsurroundin the same on its upper and lower sides an its innercircumferential edge and having the portion adjacent the inner edge ofsaid ring reduced in thickness.

7. A packing comprising a metallic ring, and a tubular woven fabriccovering surroundin the same on its upper and-lower sides and its innercircumferential edge and having the portions thereof on the upper andlower sides of said ring filled with a suitable packing material.

8. A packing comprising a flexible ring having a fabric containinglubricant and from the center of width of which the'lubrieating materialis; substantially, removed.

9. A. packing comprising a flexible ring having a fabric envelop andlubricant filler, the transaxial edges of which are made thicker thanthe'portion between the same;

In witness whereof we have hereunto set our hands this 30th day of June,1909.
